I have a 93 toy 4x4 with a 22re and ever since I have had it , it has had a little sugring thing and I am not sure if it drawin vacum off the brake master cylinder but everytime I push on the breaks it reves high and low and this does it when you start it up to warm up and ideas?????

Please help me before I sell it

what does it idle at ?

 

does the idle bounce when your just sitting there with the brake is on? but if you let off the brake, it idles fine?

 

Both the idle goes up and down when the brake is on and goes faster when you apply the brake too, and it idle up and down when the brake isn't applied.

I don't have a tac to see what it idles at.

This one pretty well nails it:

Search idle surge for more posts. Pretty common issue apparently and most likely not something that will wind up causing a premature truck sale ;>)

 

Thanks I just read it and will work on it in the morning.

 

Try checking the coolant level first. Top off if necessary.
